新型生物材料过滤器。

Science. 1964 Jan 17;143(3603):249-50. doi: 10.1126/science.143.3603.249.

Thin plastic sieves with precisely controlled hole size and density can be made by irradiating plastic films with fission fragments and etching out the material traversed by the fragments. These filters may be used for the nondestructive separation of cells of closely similar sizes.

可以用裂变碎片辐照塑料薄膜，并腐蚀掉碎片穿过的材料，从而制造出具有精确控制的孔径和密度的薄塑料筛。这些过滤器可用于对大小非常接近的细胞进行非破坏性分离。
